I'm with Evo (also passed all the PPL and IMC examinations first time), and could not, and still cannot, believe they were so easy. (Oh, and I might add that I know nothing of car mechanics, etc.: I merely drive the things and expect qualified mechanical practitioners to sort them out if they go wrong!)
Furthermore, I do not believe that MCQ really tests synthesis of argument and priority setting adequately. Surely these abilities, involved in producing a realistic course of action to solve a problem in real time, ought to be tested as much as memory and simple arithmetic?
At least one paper, essay based in order to give the candidate chance to express the sequence of their thought processes, and a judgment to be formed by the examiner, would surely not be too onerous.
